Fail2ban’s main function is to block selected IP addresses that may belong to hosts that are trying to breach the system’s security. It determines the hosts to be blocked by monitoring log files (e.g. /var/log/pwdfail, /var/log/auth.log, etc.) and bans any host IP that makes too many login attempts or performs any other unwanted action within a time frame defined by the administrator.
Today I want to show you some configurations that you can use to improve the security of your Apache.
